120-AFC II position adjustment problem

[diegodm]

Hi Fellows, 

 

I have the HS-1800 with 120 AFC II, and last month I had to change some worn out rollers from the carrier. 

And it seems that after reassembling the unit it has a scanning position problem. It does not fix with the "Scanning position Auto Correction".

I have dissasembled and assembled again and it corrected a bit, but it keeps happening that little by little the roll ends up with a position difference. 

 

Any advice from those who have run into this problem? It is related to the first belt that comes out from the motor. But I have no clue on how to adjust it perfectly.

 

Thanks in advance!

Diego.
